Martin Müller et al. have compiled a dataset of the costs and revenues of three recurring “mega-events”: the Summer Olympic Games, Winter Olympic Games, and FIFA Men’s World Cup. For each event between 1964 and 2018, it indicates the number of athletes, number of accredited media, venue costs, organization costs, ticketing revenue, broadcast revenue, and sponsorship revenue.
